Description gorilla.maguila 2011-09-09 08:42:58 UTC 
When using nouevau driver you can see weird pixels and extrange colour transitions on screen (See image attachment).

I have taken some pictures with my mobile, because If I would enclose a screenshot under nouveau you wouldn't appreciate these visuals effects.

It's not happening when using the blob.

I'm using mesa 7.11 under kernel 3.0.4 in archlinux x64, I think its been happening every time I have used nouveau driver, If I am not mistaken since kernel 2.6.35.

I don't see weird pixels, but I do see the colour transitions, i.e. that dithering seems to be disabled - http://nouveau.freedesktop.org/wiki/Dithering
